The Izaak Walton League’s Save Our Streams (SOS) program helps people just like you check water quality in local creeks and streams. Share your findings with the League, and we can get a clear picture of water quality across the country – the first step in crafting water quality solutions that work. We can also help you restore your stream to good health.
Our new video guide to identifying macroinvertebrates will help you become a bug ID expert (or at least be able to tell a dragonfly from a dobsonfly!). Includes photos and illustrations of the critters we use to measure water quality, plus identifying features and interesting tidbits. Hosted by IWLA Clean Water Program Director Leah Miller.
